PAPER FASTENER.

Application filed Hay 14, 1927. Serial No. 191,432.

The invention relates to a paper fastener, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel features of construction pointed out in the claim for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects of the invention are to eliminate the losses, inconveniences and delays incident to the misplacement of documents 1n files resulting from the unintentional clipping of papers with documents alread)7 gathered in a clip for quite another file, as is very commonly experienced in Government oflices, railway offices, legal Vand other professional and business offices; to furnish to the public at large a particularly efficient enclosure fastener for letters, easily removable as compared with the pinch form of fastener commonly used in business oiices and which usually destroy the original condition of both letter and enclosure; to assist 'l mailing clerks in their work and insure the correct enclosures in the right envelope; to provide a paper fastener or clip that will combine the advantages of the well known brass fastener and the well known clip and avoid the inconveniences of either and at the same time reduce the cost of production to the minimum; and generally to provide a simple, universal and eiiicient fastener within the reach of all consumers in an economic` sense.

In the drawings, Figure 1 is a perspective view of the fastener ready for use.

Figure 2 is a plan view of the blank. Figure 3 is a perspective view of the fastener in use.

Figure 4; is an enlarged sectional view of the fastener gripping the papers.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, the back 10, 5 the front 1.1 and the locking spike 12 are formed of one piece of sheet metal, preferably brass though any metal having reasonably iexible properties will be equally eiiicacious in carrying out the objects of this invention.v

The front 11 is turned over the back 10 at the bend 13 and the front is forined with the extension 14 having the slot 15 and making the front 11 reach laterally beyond the back 5 with the opening formed by the slot 15 in alignment with the edge of the back 10 and over the spike 12 turned up from said back 10 and made either pointed as shown at 17 or round Aas may be found most desirable in the various professions, industriesY and arts for the filing or attachmentof documents, said back 10 having the extension 18.

In the use of this invention, the letter and enclosures or other'grouped documents are inserted between the front and the back pieces and the spike bent upwardly and project-ed thro-ugh the papers and through the slot- 15 and then bent over the front piece. The grouped papers at their edges reach up to the bend 13, so that lateral displacement of the papers is by no means likely thereby effecting a neat and efficient Group of papers, that may be increased by additional papers or reduced by the removal of papers as found convenient in the office routine.

VWhat I claim is In a f paper fastener, a sheet of flexible metal bent to form a back having a spike projection'from one edge and a front having 80 a lateral extension slotted to receive said spike.
